REINFOBCED STRUCTURAL BUILBI'NG-SECTIN.

To all whom t may concern:

Be it known that I, ARTHUR WHITE, re-

' siding in Sheboygan Falls, in the county of Sheboygan and State of Wisconsin, have invented new and useful Improvements Reinforced Structural Building-Sectio:ns,ofA

which the following is a description, reference being had to the accompanying drawings, which arel a part of this specification.l This invention relates to improvements in more particularly to that class in which buildings are constructed of interlocking building blocks and the floors and roof thereof formed of reinforced sections or slabs of cementitious material shaped to interlock with adjacent sections and also with the vertical walls of the building.`

One of the objects of this invention is tov provide floor, roof or ceiling building sections formed of cementitious material having longitudinal reinforcing metal bars molded therein which are adapted to be anchored to the vertical walls or partitions of vthe building of which they forma part.

Afurther object of the invention is to provide a floor, roof or ceiling building section formed of cementitious material having transverse reinforcing metal strips molded therein which are constructed to be locked to the metal reinforcing strips of adjacent sections.

A further object of the invention is to provide a floor or'ceiling building section having longitudinal and transverse reinforcing metal bars and strips molded therein which are rigidly connected together to form all of 'tlie reinforcements of the sections into a unitary structure which is anchored to the walls of the building, when assembled together to form a ioor or ceiling.

particularly adapted foruse-V in construct-- ing '.floors, roofs and ceilings of buildings, it :is alo adapted for other uses in which it may-be .employed with advantage.

With the above, and other objects in view, A nth` 'invention consists.' of the structural "ection asset' forth in the claims arts and combinations, and all nts thereof. hei-accompanying drawing, in which 4'the same reference characters indicate the #5 same parts in all of the views, ,Figure l is a verticalv sectional .view of fragments of a Specilcatiou of Letters Patent. application mea January 2a, 1910, semi iro. 539,454.

wall'y and partitions 'of' a building having the improved floor section, the floor 4sections being 'in longitudinal section; Fig.` 2 is a plan viewof several of the sections joined 'togetherg` parts broken away and other parts in sectinngFig. 3 is a transverse sectional view takenv on line 3.-.-3 of Fig. 1, of two of the sections joined together.; Fig. 4 is a lslmilarviewl thereof taken on line 4:-4 of Fig'. 1;4 Fig. 5-is a transverse sectionalview reinforcing strips; and Fig. 6 is a transiing a modified form ofl connection between the longitudinal rod` and the transverse stri-p. f

Referring to the drawings the numeral ll indicates the outside vertical wall of a building, and 11 the vertical partition wall thereof 'which are formed of interlocking 'blocks 12 provided with tongued and groovedportions 13 and 14 respectively.

The. floor sections or slabs 15- may be of any desirable size and form found to be desirable in constructing buildings. The body of the sections 15 are formed of any ".cementitious 'material that may be molded in a plast-ic state in the form desired, and when hardened forms a ri 'dV structure adapted to withstand the strain to which it vided with tongues andgrooves 16 and 17 formed on the side edges thereof which arevr adapted to engage the tongues and grooves ofadjacent vsections when assembled together to form a Wall, roof or ceiling and form substantially Water-proof joints. The

vided `with transverse tongues `18 and With one or more reinforcing rods 1 20 which the sections a'nd at one end project',- in the form of an eye 2l, beyondthe ,endto form surface of the section and extend downwardly at an incline to the medial portion of the section and near the lower surface is subjected. The sections of slabs are pro-` sections which are adapted to have their ends rest on the outside .walls ofthe build-` ing and form part of the wall itself are proj-` .extendA substantially-.the l.entire `lengthof j of two sections having modified .forms of verse sectional view of a floor section showgrooves 19 positioned toregister and en.- v; gage the tongues and4 grooves 13 -and..14,. ofthe buildingblocks formingfthe outsideV wall to anchor said sectionsI to `the. walls. Each of` these liolorsections are provided .ico

va means for connecting :the ends.l of ,twoV

sections together. .The -endslof thesefrein- Vforcing rods aiepositioned near.- the. upper l -eyes to `'with eyes 24 which are embedd connected together are provided with registering recesses 22 to accommodate the projecting eyes of the rods of opposite sections and` end ins 23 which exten through said ind the ends of the sections together and alsov project a suilicient distance above and below the sections to enter the blocks of the partition wall 11 and anchor the said sections to said partition. The

ends ofthe rods 20 which extend to the exterior ends of the sections 15 are rovided section and the sections have openings 25 registering therewith in which anchor pins 26 are inserted. These pins extend through the openings and the eyes and project into the building blocks formin the outside wall to serve as additional anc oring means for said sections. The sections15 are also provided with transverse reinforcing metal strips or bars 27 which are embedded in the sections and are adapted to be connected to the transverse strips of adjacent sections. In the preferred form, the transverse reinforcing strips are each formed of a si le strip 'of metal bent over upon itself with the loop 28 shaped to conform to the tongue 16 of the section and with the ends 29 diverged to conform to the groove 17 of the section. The tongue. and' grooved portions of the reinforcing strips are shaped to lie flush with the surfaces of the sections forming the tongues and grooves so that smooth connecting surfaces are presented for engagement with each other. Each longitudina tongue and grooved portion of the strips and of the sections are rovided with opnings 30 which register with each other w en the sections are assembled together for the insertion of locking pins 31 which serve to lock the sections and also the transverse strips together. The two portions of the transverse strips are positioned respectively above and below the lon l'tudinal reinforcin rods and are clam thereto by means o bolts 32 which pass through openings in said strips alongside of the rods and draw said strips toEet er and clamp the rods therebetween. T ei upper portionof the strip is bent to form recesses 33 to more securely clamp the rods. The upper portions of the transverse strips positioned adjacent to the exterior ends of the sections are bent upwardly to engage the eyed ends of the longitudinal rods and are fastened thereto b the anchoring 26 before mentione which extend through the eyes of said rods and throu 1. openings inthe strips. Additional rein orcing strips 34 are rovided for the ends which are 'tioned immediately below the longitudina rods and in the v the upwardly bent portions and through which the pins 26 also pass.

In the modified form shownin Fig. 5 the reinforcing transverse stri s 35 are of siii le thicknesses and extend be ow the lon itu inal rods 20 and are not connected t ereto. The form shown in Fig. 6 is likewise provided iith a s' le thickness transverse strip and differs om the form shown in Fig. 5 in that only one longitudinal reinforcing rod is shown which is clam ed to the transverse rod 36 b means of a olt 37 having a hooked end`w ich enga es the rod.

- In some cases the sections wil have both ends of similar construction so that a number of sections may be connected together inside of a building or one section may extend. from wall to wall and be anchored thereto.

A strip 38 may be used, if desired, to form a to e coveringthe joint and in which case t e block resting on the joint will be provided with a corresponding groove to engage said tongue andy the pins 23 will extend into said strip.

The reinforcing rods and strips are n iold-k ed in the sections while said sections are in a plastic state From the foregoing description, it will be seen that a reinforced structural building section is provided which is strong and durable and when assembled to form a floor or roof or other parts of a building, the sections and their reinforcements are securely locked together in both longitudinal and transverse directions and the sections are also anchored to the walls and partitions to form substantially a unitary structure which will withstand any strain which it, may be 'subjected to.
